First of all, forgive me for my english.
I would like to ask if any one can help me find a chassis connector that can handles 30a at about 80vdc.
I found some industrial connectors that can handle 32a at 220vac, but i would like to ask if i will have any problem using them at 80vdc.
Thanks in advance.

The current rating is obviously the max. amount of current the pins connection will pass, this is regardless of what voltage, the voltage usually refer's to the insulation rating of the connector, so as long as it is below 220v, you should be OK.

Thank you Al for clearing this out for me. Have a nice day.
